Nowadays, total laryngectomy is primarily performed for advanced laryngeal cancers with involvement of the laryngeal skeleton and/or extending outside the larynx, hypo- or oropharynx. Another field of application is represented by salvage surgery following chemo-radiation therapy failure. In both these situations, laryngectomy is achieved by therapeutic or elective neck dissection(1-2) . This procedure is carried out by adopting an open trans cervical approach.

BACKGROUND: Self-expandable metal stent (SEMS) insertion and percutaneous gastrostomy (PG) feeding are commonly used for patients with esophageal cancer and dysphagia. This study aimed to compare outcomes between SEMS insertion and PG feeding for them. METHODS: We retrospectively analyzed 308 patients with esophageal cancer who underwent fully covered SEMS insertion (stent group) or PG (gastrostomy group) for dysphagia due to tumor. Patients with other causes of dysphagia, such as radiation-induced or postoperative stricture, were excluded from the study...

Homeobox containing 1 (HMBOX1) modulates telomere length in various types of tumor cells by binding to double‑stranded telomeric DNA. There is a negative correlation between telomere length and radiosensitivity in tumor cells. In the present study, we aimed to investigate the relationship among HMBOX1, telomere and radiosensitivity in cervical cancer cells. Lentivirus-based shRNAs were used to establish stable transfected cell lines in which protein and mRNA levels of HMBOX1 were notably decreased. Knockdown of HMBOX1 increased the radiosensitivity of HeLa and C33A cells...

RAD51 is one of the pivotal enzymes for DNA double-strand break (DSB) repair by the homologous recombination (HR) pathway, which implies it as a promising and novel target for cancer therapy. Recent findings have indicated RAD51 protein is overexpressed in a variety of tumors. The high-expression of RAD51 is related to poor prognosis. RAD51 is involved in the repair of DNA damage and the generation of genetic diversity by an evolutionarily conserved mechanism. However, the exact mechanism of Rad51 in the progression of cervical cancer remains unclear...

Neoadjuvant (or induction) chemotherapy can be used for cervical cancer patients with locally advanced disease; this treatment is followed by radical surgery and/or radiation therapy. Cisplatin is considered to be the most active platinum agent drug for this cancer, with a response rate of 20%. In order to understand how the cisplatin treatment affects the stress response, in this work, we performed an exploratory study to analyze a number of stress proteins before and after cisplatin neoadjuvant chemotherapy...

PURPOSE: Brachytherapy (BT) techniques have historically used a two-dimensional nonvolumetric (NV) system involving dose prescribed to a point fixed in space. We compared dosimetric, toxicity, and oncologic outcomes for volumetric planning (3DV) versus CT point-based planning. METHODS AND MATERIALS: Patients treated with external beam radiation therapy and high dose rate (HDR) intracavitary BT were included (n = 71). Patients planned with NV BT treated from 2009 to 2011 (n = 37) were compared to patients planned with 3DV BT treated from 2012 to 2014 (n = 34)...

PURPOSE: The standard chemoradiation therapy currently used for locally advanced cervical cancer (LACC) patients does not reflect the biological heterogeneity of this disease, and there is an increasing need for the development of biomarkers that can help guide the individualized treatment regimens. The purpose of this study was to investigate the prognostic value of the integration pattern of human papillomavirus (HPV) in LACC patients. METHODS AND MATERIALS: The HPV integration pattern was determined by in situ hybridization and polymerase chain reaction, and the tumors were classified as the episomal pattern (group A), as the single-copy integrated or multicopy tandem repetition-integrated pattern (group B), or as undetectable HPV (group C)...

Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden...

PURPOSE: Biological modelling of thermoradiotherapy may further improve patient selection and treatment plan optimisation, but requires a model that describes the biological effect as a function of variables that affect treatment outcome (e.g. temperature, radiation dose). This study aimed to establish such a model and its parameters. Additionally, a clinical example was presented to illustrate the application. METHODS: Cell survival assays were performed at various combinations of radiation dose (0-8 Gy), temperature (37-42 °C), time interval (0-4 h) and treatment sequence (radiotherapy before/after hyperthermia) for two cervical cancer cell lines (SiHa and HeLa)...
